Remove a vWitness definition
First, disable the vWitness definition (Disable the use of a vWitness definition) and then remove it:
symcfg -sid SymmID remove -witness WitnessName
Example
To remove the vWitness definition named metrovw1 from storage array 1234:
symcfg -sid 1234 disable -witness metrovw1 -force symcfg -sid 1234 remove -witness metrovw1
